NATO members reaffirmed their continued support for Ukraine after the June 25 summit in The Hague. They also pledged to increase alliance defense spending until 2035 amid the threat from Russia, says in the final declaration.

Assistance that directly contributes to Ukraine's defense and the development of its defense industry will be included in the calculation of allied defense spending.

"Recognizing that Ukraine's security contributes to their own security, Allies reaffirm their long-term support for Ukraine, as they have sovereignly pledged to do," the document says .

NATO members have called Russia a "long-term threat" to Euro-Atlantic security, as well as the threat of terrorism. Against this backdrop, NATO member states have decided to increase the annual share of GDP spent on defense to 5% by 2035. This includes at least 3.5% of GDP for military spending and another 1.5% for the protection of critical infrastructure.

"These investments will ensure that the Alliance has the forces, capabilities, resources, infrastructure, readiness and resilience necessary to deter and defend, prevent and manage crises, and provide cooperative security," the declaration says .

In addition, NATO countries reaffirmed their "unwavering commitment" to defend each other in the event of an attack, based on Article 5 of the collective defense treaty.

"An attack on one is an attack on all," the document says.

The Declaration was endorsed by 32 NATO leaders, including US President Donald Trump.
